How to use DataStore2 - Data Store caching and data loss prevention

#1850

Three Questions:
1: Am I able to use DataStore2.Combine more than once? if so how is that benefitable?

2: Is there a way to make a stat that is already in existence, instead of making an instance?

3: Is there a way to assign a dataStore to a Value that is inside a UI element, but that element is cloned many times, like an Upgrade system that has a “CurrentUpgrade” value inside the UI, And I don’t want my datastore to interfere with other instances of the “CurrentUpgarde”?

You can DataStore2.Combine("DATA", unpack(dataStoreKeys)) and have dataStoreKeys be a table.

Yes. As long as a key is combined before use.

Yes, it’s the exact same thing as using it in one line.

I don’t know what you mean. DataStore2 doesn’t do anything with regards to “stats”.

DataStore2 does not use instances. Do this however else you’d normally do it.

Yo I need help

local Players = game:GetService("Players")

local DS2 = require(game.ServerScriptService.DataStore2)

DS2.Combine("DATA","Element","HasPillar")

Players.PlayerAdded:Connect(function(Player)
	local ElementStore = DS2("ElementS",Player)
	local HasPillarStore = DS2("HasPillar",Player)
	local DataFolder = Instance.new("Folder")
	DataFolder.Name = "Data"
	
	local Element = Instance.new("StringValue")
	Element.Name = "Element"
	Element.Parent = DataFolder
	Element.Value = ElementStore:Get("Fire")
	
	ElementStore:OnUpdate(function(newVal)
		Element.Value = newVal
	end)
	

	local HasPillar = Instance.new("BoolValue")
	HasPillar.Name = "HasPillar"
	HasPillar.Parent = DataFolder
	HasPillarStore.Value = HasPillarStore:Get(false)

	HasPillarStore:OnUpdate(function(newVal)
		HasPillar.Value = newVal
	end)
	
	DataFolder.Parent = Player
	
	
end)

game.Players.PlayerAdded:Connect(function(Player)
	local joinData = Player:GetJoinData()
	

	local teleportData = joinData.TeleportData
	
	if teleportData then
		
		if teleportData.Won then
		
			repeat wait() until Player.Character
			local c = Player.Character
			local DS2 = require(game.ServerScriptService.DataStore2)
			local HasPillarStore = DS2("HasPillar",Player)
			print("Newest")
			HasPillarStore:Set(true)
			c:WaitForChild("HumanoidRootPart").CFrame = workspace.NPCs["vShanksv"].Spawn.CFrame
		elseif teleportData.Won == false then
			repeat wait() until Player.Character
			local c = Player.Character
			c:WaitForChild("HumanoidRootPart").CFrame = workspace.NPCs["vShanksv"].Spawn.CFrame
			
		end
		
	end
end)

its printing so i know it reached but it doesnt work

Hey, we’re having a problem regarding the use of DataStore in a game that we’re working on.

Basically, the game loads the data of the player when playing in Studio, but it doesn’t when doing so with the Roblox Launcher. If you would like more details about this, here’s the post: Datastores, data in game is different then what is being returned in studio - Help and Feedback / Scripting Support - DevForum | Roblox

Suggestion

A DataStore2 edit feature or plugin so we can easily modify DataStore2 data, kind of ike @sleitnick 's DataStore Editor plugin

Can you use two separate tables for DataStore2? My game uses a save system where players’ statistics/preferences (e.g. coins, UI Size, Music Volume) and their inventory (all the tools they own) are separated, as I keep adding new entries to both tables through updates, making a unification of both very displeasing to deal with, as it would mean I’d have to reflush all entries in my system every time I want to add something to one of the two tables.
Thanks in advance

#1857

The best way to do this is having your keys be the save files themselves, which DataStore2 does fine, except a tad non-ergonomically.

#1858

therefore I put the tables instead of the keys?
there were actully two different datastore values

#1859

nvm, found out how to deal with all these spooky technical terms. it’s surprisingly easy!

can you use it in local script too? like getting the number or string i guess not but you can create a folder with every properties but in numbervalue or in stringvalue

#1862

Hi! So it seems like DataStore2 doesn’t work with Deferred events. Will this be getting fixed?

Workspace.SignalBehavior will be Deferred by default pretty soon.

#1863

No, it only works on a server script as it is a DataStore system. Also, Attributes are a lot more reliable than BaseValues.

#1864

This would’ve been really useful if people used it today, Roblox has been out for 2 hours and I belive DS2 works perfectly fine! :upside_down_face:

#1865

I don’t think it’ll be default “pretty soon”.

It’s something I’m going to look into at some point. File an issue on GitHub before I forget.

#1866

When I looked on the Saving Methods on the GitHub Page, It said that the saving method is Ordered Backups by default, does that mean it is kind of the same as DataStoreService:GetOrderedDataStore("GlobalLeaderboard_" .. statsName)
or is Ordered Backups Completely different, if it is completely Different, how am I able to make a ordered list of the dataFrom all the players?

#1867

DataStore2 provides no way of using ordered data stores, since I’ve never needed them. The saving method is an implementation detail.

I’m having a problem, it doesn’t seem to be saving the data correcty ( I use DataStore(“CustomInfo”,plr):Set(table) print(DataStore2(“CustomInfo”,plr):Get() and it does print the correct data, however when I rejoin, it prints a random data that I’ve never saved? Thank you for reading.

#1869

Currently having trouble, could I get some help? It seems that whenever I save the data I can’t get the data again from a place inside of the game. I use the same key and yet I’m still having trouble. Is there anything I’m missing?
